Hello,
A private chat with a group of 4 users has been created under private messages. One user does not see this chat and can only enter this chat with the link from the e-mail message. This user cannot write anything in this chat and receives the message "Replies are disabled".
All authorizations are set correctly and this user can write in the other private chats without any problems.
How can I solve this problem?

Many thanks in advance
Dim
